Abstract

Mating relationships between Chinese biological species and North American species of Armillaria.

Abstract

A pairing tests of Armillaria between 3 Chinese Biological Species (CBS) and 6 North American Biological Species (NABS) were conducted. A total of 38 monospore isolates from Northeast China, which are representative of CBS A, CBS C and CBS D, were mated with tested strains of A. sinapina, A. calvescens, A. gemina, A. nabsnona, A. ostoyae and NABS X. CBS A was identified as A. sinapina, CBS C was intersterile belonging to Asian-specific species, and CBS D was interfertile with 2 isolates of A. ostoyae and was identified as A. ostoyae.
